Linear systems can optionally be solved on the GPU using the CULA Dense toolkit.

Download and install the full edition of CULA. The full edition is required since the free edition only has single precision functions. The full edition is free for academic use, but requires registration.

As recommended by the installation, set the environment variables CULA_ROOT and CULA_INC_PATH to point to the CULA root and include directories. Also, add the CULA library directory to your LD_LIBRARY_PATH.
